Where Pi works
- Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
- Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
- Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
- Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
